It's a spectrum, but personally I believe that the e and i in reference to cognitive function has very little to do with social energy, as the terms are more commonly used. So for the purpose of discussion, I'll set sociability aside.

I'm an INFJ, which is to say I possess dominant Ni and auxiliary Fe. If we acknowledge that I/E is a spectrum, that means I have an ENFP side, since that would be dominant Ne and auxiliary Fi. And that actually feels very true for me.

Talking specifically about the judging functions, my comfort place is (and will probably always be) to defer to the group, to offer my cheek for a slap if it means ultimate harmony. But I won't always do that. Because I am not just my two most-used traits.

To give an even more concrete example... I fell out with a friend last year. My immediate impulse was to roll over, to invite criticism, to do whatever it took to repair the relationship, even if it meant questioning my own reality and perception of events. I gaslit myself.

As time passed, I used the reassurance from better friends to rely more on my less prominent Fi side. I developed the bravery, confidence and self-respect to confront that friend and stand up for myself. To give ground where it was earned, to be humble where I had messed up...

But to stand by the times when I was right, or just, or where I had been unjustly maligned. Fi was not my default, but I'm capable of it, and I am healthier for strengthening it. Likewise, sometimes Fe doms grow by learning when to give way to others and take one for the team.

Now, as to extroversion, introversion and ambiversion as they're more commonly used. I do still think they have a place in Jung's method, but it's just less stark than http://16personalities.com  would have people believe.
